When Power Goes To Your Head, It May Shut Out Your Heart

Even the smallest dose of power can change a person. You've probably seen it. Someone gets a promotion or a bit of fame and then, suddenly, they're a little less friendly to the people beneath them.

So here's a question that may seem too simple: Why?

If you ask a psychologist, he or she may tell you that the powerful are simply too busy. They don't have the time to fully attend to their less powerful counterparts.

But if you ask Sukhvinder Obhi, a neuroscientist at Wilfrid Laurier University in Ontario, Canada, he might give you another explanation: Power fundamentally changes how the brain operates.

Obhi and his colleagues, Jeremy Hogeveen and Michael Inzlicht, have a showing evidence to support that claim.

It turns out, feeling powerless boosted the mirror system — people empathized highly. But, Obhi says, "when people were feeling powerful, the signal wasn't very high at all."

So when people felt power, they really did have more trouble getting inside another person's head.

"What we're finding is power diminishes all varieties of empathy," says Dacher Keltner, a social psychologist at University of California, Berkeley, not involved in the new study. He says these results fit a trend within psychological research.
